Abstract
A disposable personal care cleansing article is provided having a cleansing composition adjacent to a water insoluble substrate formed of a fibrous web. A plurality of slits having a length ranging from about 6 to 40 mm are cut into the web. The slits allow the article to expand when a consumer applies the article to cleanse the body under a flow of water.
Claims
exact text as granted — not AI-modified1. A personal care cleansing article comprising;
(i) a water insoluble synthetic fibered substrate formed of a web with a plurality of slits cut through and into the substrate and having a length ranging from about 6 to about 40 mm and a width no larger than about 2 mm; and
(ii) a cleansing composition adjacent the substrate comprising from about 0.1% to about 95% of lathering surfactants by weight of the composition.
2. The article according to claim I wherein the substrate is lofty having a Loft-Soft Ratio greater than 1.1.
3. The article according to claim 1 wherein the slits have a length ranging from about 10 to about 25 mm.
